The extensions of rays emitted by a source and reflected in two incident plane mirrors one or more times, cross at points (the virtual images of the source) that appear as new sources to an observer. This Demonstration shows how many and which images are formed, also in relation to the number of reflections considered, as the angle between the two mirrors decreases from to 0 radians. The formation of new images occurs at for each natural number .
